attached to the access panel. The dryer vent should not exceed a maximum length of 4 feet primarily because the buildup of condensation increases the time required to dry the clothes.

Troubleshooting

You need to be acquainted with the operation and functioning of both the mechanical and electrical systems. Although the various types of clothes dryers may differ in appearance and location of controls, they all operate on the same principles and are fundamentally similar in servicing. Clothes dryer timers are quite similar to those on an automatic washing machine, while thermostats used in automatic dryers are the same type as those used on electric ranges.

Since the only moving parts consist of the motor, drive, drum, and exhaust fan, the clothes dryer, when properly installed, should give years of trouble-free service. When called on, the service personnel should be familiar with the recommendations and specifications of the particular manufacturer's service manual to replace any worn-out or faulty component correctly. When a dryer does not operate properly, always try the service manual first. However, table U of appendix II may be used for further troubleshooting and repair should it become necessary.
